To all whom it may concern:

Be it known that I, LEWIS J. HANSON, a citizen of the United States, residing at Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Car Replacers, of which the following is a specification. i

This invention relates to improvements in car replacers and more particularly to a car replacer for replacing the wheels of street railway cars on surface tracks.

One of the objects 0]": the invention is to provide a combined left and right hand onepiece plate adapted to be used either between the rails or outside of either rail, the rail chosen being determined by the natureof the derailment. In cases where a wheel is outside of a rail with the flange of the Wheel abutting against a paving block or. other obstruction, this plate may be used to free the same.

Another object of the invention is to provide a car replacer plate with a number of downwardly extending lugs adapted to engage the groove formed in the paving or other street surface to allow for the flange of the car wheels, or in case of girder rails,

the lugs may be placed against the flange of the rail itself. Said lugs are positioned in such manner as to permit the plate to be used in various positions relatively to the rail. If the derailed wheel lies close to the rail, three lugs at one side of the plate may he placed in said groove or against said flange while if the derailed wheel is some distance from the rail, then one of the end lugs only is placed in the groove or against the flange to permit the replacer plate to he swung into the proper position to receive the car wheel.

A further object of the provide a car replacer having a number of grooves in its upper surface, which may be usedto replace car wheels lying at varying distances from the rail.

Another object of the invention is to furnish a car replacer plate oiirelatively light structure to reduce weight, but suficiently strong to bear the weight of a street railway car.

\Nith the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the inveninvention is to 7 Serial 672,546.

tion consists in the novel ieatureshereim after described in detail, illustrated-in the accompanying drawing and more particu-;

larly pointed out in the appended claims.

Referring to the drawing: Figure 1 is a top plan view of the replacer. Fig. 2 is a side view of the same. 7 Fig. 3. is a front end view. Fig. 4 is a rear end view.

In the drawing the .replacer plate con sists of a single piece of metal formed by casting or the like, and in practice thisplateis about twelve inches long, nine inches wide and about two and one-half inches highat its peak. r

The main portion of the plate is V inclined,

upwardly and rearwardly from, the front the 'replacer is placed for instance at the left hand side of thetrack rails, the portion of the ridge designated P will engage the flange of the wheel while the wheel is traveling up, the inclined surface of the plate, and gradually force the wheel outwardly toward the right as the wheel moves up the incline toward the rear edge'of the rep-lacer plate. On the other hand if the replacer is placed at the right hand side of the track, the portion 4 of the ridge functions to force the car wheel toward the;

track. I

Ridges 7 extend upwardly from the opposite side edgesof the plate, and shorter verticalridges 8 extend upwardly from the plate and are spaced from the ridges 7 to provide parallel grooves 9. If the wheel to be replaced liesclose to thetrack rail, then the groove 9 maybe employed to guide the wheel as the latter moves up the incline and toward the rear edge 6- of the plate.

Still shorter ridges 8 are arranged between the ridge land these ridges 8 are inclined relatively to the ridges 8 to provide substantially V-shaped grooves 9, which may be employed to guide the wheel in case the wheel lies too far from the track to be received by pne of the grooves 9. V

A triangular portion of the plate is removed as shown at 5 in order to reduce weight, and a cross-bar 6 extends across the rear end of the plateeto'connect thetwo legs formed by removing the portion 5.

The reference character 1G designates the plane of the upper surface of the plate from the flat surface 8 to the peak 2, while the reference character 11 designates the plane forming the upper edges of the ridges 7, 8 and 8.

Downwardly extending flanges or side bars 4 form the side edges of the plate and the space between these side bars and beneath the inclined body of the plate, is hollowed out to reduce weight.

The rear end or" the inclined surface of the body of the plate merges into convex surfaces 6 which extend from the peak 2 of the inclined surface to the rear edge 6 of the plate. These convex surfaces 6 in practice extend upwardly about two inches, so acar wheel passing Over the peak 2 and down the convexed surface 6 will glide without jcrring or breaking the flange of the car wheel.

The side bars F are provided with depending spaced lugs 12, one of these lugs being arranged near each end of the side bar, and the other lug being arranged inter mediate the ends oi the side bar. These lugs are so arranged that ii" the rail wheel lies close to the track, all three lugs at one edge of the plate may be inserted in the track groove or in the groove in the pavement adjacent the track, and these lugs will then prevent shifting of the plate while the car wheel is riding over said plate. It the derailed wheel lies some distance from the track rail, then one of the end lugs a ranged near the rear end 6 of the plate, may be inserted in the track groove or in the pavement groove adjacent the track, and the plate ma y be swung about this lug to bring the plate into a position to receive the derailed wheel.

Grooves 1 are arranged between the ridges 8 the ridge 4.- and these grooves lead from the entrance or running-on end of the plate to the right and left corners respectively or running-oft" ends of the plate, and these running-oil ends are convexed orrounded, as before stated, to facilitate gliding the wheel on to the rail.

The ridges 8 and 8 in addition to functioning as guides, also strengthen the body of the plate. The hollowed out portion of eena-0e the plate beneath the body and between the side bars facilitate the arrangement of the replacer over obstructions formed by paving blocks and the like. 7

From the foregoing it is believed that the construction, operation and advantages of the invention may be readily understood without further description, and it is apparent that changes may be made in the details illustrated without departing from the spirit of the invention as expressed in the claims.

What I claim and desire to secure by Letters-Patcnt is:

l. A car replace-r comprising a plate having its upper surface inclined upwardly and rearwardly to point adjacent the rear edge of said plate, and inclined downwardly from this point to the rear edge, a ii-shaped ridge extending upwardly from said plate and having its point adjaccntto the front edge of the plate and its ends terminating at the rear edge of the plate, and a plurality of grooves arranged in the upper surfaces of said plate between said ridge and the side edges of the plate. 7

2. A. car replacer as claimed in claim 1 in which said grooves are formed partially by upwardly extending ridges integral with the plate.

3. A car replacer as claimed in claim 1 in which said grooves are formed partially by upwardly extending ridges integral with the plate, certain'of the last mentioned" ridges' being substantially parallel to the side edges of the plate, and others of said last mentioned ridges being arranged at angles to the parallel ridges.

a. A car replacer as claimed in claim 1 in which a space is provided between the legs of the ll-shaped ridge to reduce weight.

5. A car replacer as claimed in claim 1 including pendentlugs arranged at the side edges of the plate and spaced apart.

' 6. A car replacer comprising a plate having its upper surface inclined upwardly and rearwardly from one end of the plate to a position adjacent the other end of the plate, parallel ridges extending upwardly from the opposite side portions of the plate, a V-shaped ridge extending upwardly from the upper surface of the plate, having its point merging into one end of the plate and having its lugs diverging toward the opposite end of the plate, and intermediate ridges arranged between the V-shaped ridge said side ridges.

In testimony whereof I afiix my signature.

LEWIS J. HANSON.
